Did a large batch of these for a big collector customer of mine got three kits left over. Suit stern sam machines. You do need a little bit of technical ability, (but not a lot) as the existing 8" sub fixing studs need re-locating. And the sub placed just right so it avoids the support brackets. Kit includes a set of spacers if you do not have speaker leds or speaker plastic inserts.
Or a set of longer screws if you do....trade price to members £40 plus £9.00 postage.
